First of all you need to work and learn more about UpdatePanel samples. How it works and how to use it.

Search for more samples on web. Also, the use of AsyncPostBackTrigger.

Secondly, how to solve your issue..

1. Place FileUpload, Button control outside UpdatePanel. This way you will able to get File Path.

2. refer this article: Disable a submit button during Post Back

yes, i tried..but i didn't get. cause upload control & change file btn are together. and if i removed update pnl then file is not uploading...hence i used update panel for change btn only. & i m using update panl for save btn also. then file gets uploaded but when i click on change btn, page gets postback, which i don't want.
i used this code in both update pnl
<Triggers>
<asp:PostBackTrigger ControlID="change_btn" /> Triggers>
Suggest any code. thanx

First of all its not recommended of using an FileUplaod control in UpdatePanel.
Put the FileUpload outside the UpdatePanel.

Use Update Panel, File Upload Control and use a PostBackTrigger Control to force a postback only for the File Upload Control
Otherwise File Upload wont work in Update Panel.
Button2 -> Which you click once you select the file from the dialog box.
<Triggers>
<asp:PostBackTrigger ControlID="Button2" />
